摘要 |
A diamond composite combined with a cobalt-containing substrate, comprising: a sintered mass of diamond, in which practically all the diamond particles are joined immediately with adjacent particles, a mass of cobalt-containing carbide, said latter mass being larger than the former and said first and latter masses being of a same cross section at the opposed ends, and an intermediate layer of a solid material which consists of Mo, Co and C with a minor proportion of inevitable impurities and which comprises a molybdenum carbide exhibiting a melting point within 200 degrees C. of that of the first said carbide material, said layer intervening between the masses and having a total radial cross sectional area of at least 80% but not greater than 97% of that of the diamond mass and carbide masses at the joint and a thickness of, at least, 25 microns over the whole cross sectional area and method for producing the same. |
